Drilling: The use of all imported precision high-speed drilling machine, large production area, 8-axis drill at the same time drilling, efficiency and quality at the same time to ensure the auxiliary process to ensure the roughness of the empty wall, conv
At present, for PCB curing, the most suitable use or UV light source, because UV light source has the characteristics of other mercury lamps do not have, just take the light source, UV light source is a cold light source, the curing principle is that the
Although baking is the best way to improve the burst board, baking not only wastes time, but also wastes equipment and manpower, and the Tg value will decrease after baking PCB is also a problem.
All digital logic circuits can be simplified by the above three kinds of circuits, that is to say, a circuit can be composed of NAND or NOR circuits. Let's take a look at their characteristics to deduce the characteristics of digital CMOS circuits.
The common multilayer board is generally 4 or 6 layers, complexMultilayer board can reach dozens of layers.
Keyou Circuit is a dedicated to PCB rapid proofing and mass production, with high precision single side/double side/multilayer circuit board .
Many manufacturers are using ceramic COBs to process LED, because this can further reduce the cost of LED energy-saving lamps.
many times if the site sorting, rectification and other work to do, then some of the existing quality problems will improve a lot.
PCB industry is technology-intensive and capital-intensive, but it is still labor-intensive. A large number of automation equipment needs manual operation and assembly line operation. A medium-sized PCB enterprise has thousands of employees.
